Review on Deflection Compensation Methods for Machining of Thin-Walled Components

Abstract

The deflection of thin-walled components during machining will seriously affect their machining accuracy and surface quality. This paper presents a state of art review for the research in error prediction and error compensation during machining of these components. Some key techniques, such as the overall scheme, the cutting stability, the machining force modeling methodologies, the machining deformation analysis methodologies based on FEA and NC compensation methodologies, are discussed. The problems which have been highlighted in the research papers are pointed out and some problems which should be further investigated are given.
